Mint Irish Cream Brownies


I love to make these Mint Irish Cream Brownies each year for St Patrick’s Day. They taste delicious with a combination of Baileys, mint and topped with a green frosting! I love the combination of moist, chocolatey brownies with coffee flavored Baileys and a hint of mint. 

Start by whisking brownie mix, eggs, oil, and Baileys together. Bake the batter in a preheated oven for 30 minutes. Make the frosting by beating butter until light and fluffy with powdered sugar until smooth. Add Baileys, mint extract, and a pinch of salt. Tint the frosting with a few drops of green food coloring and spread on top of the brownies.  

To make Mint Irish Cream Brownies, you will need the following ingredients:

Steps to make Mint Irish Cream Brownies


Heat the oven and prepare a pan


Preheat the oven to 350 °F. Grease a 9x9 inch baking pan with cooking spray and line it with parchment paper.


Make brownie mixture


Whisk a box of brownie mix, 2 eggs, ½ a cup of oil and ½ a cup of Baileys.


Put the brownie mixture in the baking pan


Pour the brownie batter into the prepared baking pan.




Bake for about 30 minutes. Remove from the oven when a toothpick inserted comes out with some moist crumbs.


Leave to cool

Leave the brownies to cool in the pan.


Make the frosting


Beat ½ cup of butter using a handheld mixer until light and fluffy. Add 2 cups of powdered sugar and beat until smooth, light and fluffy. Add ¼ cup of Baileys, ½ a teaspoon of mint extract, and a pinch of salt. Beat the ingredients until fully combined.


Add sugar and green food coloring


Add the remaining cup of powdered sugar and a few drops of green food coloring and beat until you have a smooth green frosting.


Frost the brownies


Once the brownies have cooled, spread the frosting on top and drizzle with melted chocolate.

I made these for my husband and he loved the minty taste, he did mention that they were a little bit bland and needed more sugar added though.

Emani Hartpence

Was very good with some bland tea, I used brown sugar instead of powdered and it tasted better than store bought.

Azalea Labhart

I made this on St. pattys day and liked it more than I imagined I would, usually I avoid minty cakes and stick with things like the chocolate coffee cake, but this was worth stepping out of my comfort zone

Estefania Possemato

Making this for a co-workers birthday and already tried one, really tasty and the mint isn't too strong so it's the perfect dessert.

Anneliese Feigelson

Not only is this dessert beautiful to look at but it taste just as it looks, like heaven!

Arely Baab

These have a very rich taste but every time I tried making them they turned out to be quite dry.

Reece Barty

Wish I was better at designing cakes because the swirls turned into big dots of chocolate but doesn't matter because they all ended up in my tummy either way!

Elinor Himebauch

I absolutely love brownies and these are on my list! There is a small issue though, Bailey's is not available where I live so I used a different cream.

Christiana Beights

These are super cute and very filling, I loved them a lot!

Nahla Mastropolo

Very pleased with how these came out, will be baking them again for Easter just because it taste soo good.


Well done! Thanks for sharing recipe!
